PERPETUAL CALENDAR.

Specicaton of Letters Patent.

Patented J an. 6, 1920.

Application led March 26, 1917. Serial No. 157,351.

To all whom 'it may concern:

Be it known that I, FRANZ A. FULLER, of the city of Newark, county of Essex, and "State of New Jersey, have invented certain new and useful Improvements in Perpetual Calendars, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it pertains to make, construct, and use the same, reference being had to the accompanying drawings, and to numerals of reference thereon, forming a part of this specification.

My invention relates to improvements in perpetual calendars, which are adapted to indicate the names of the day of the week, and also the months of the year in chronological order, and has for its objects, to provide a novel device of the character indicated, whioh shall be .simple and effective in construction, comparatively inexpensive in cost, and which, by proper manipulation, will display the name of the day, its date, as well as the name of the month.

My improved calendar is of such form that it is well adapted for advertising purposes, in that the advertisements may be placed or embossed in any suitable manner upon the front thereof. With this end in view, my invention consists in certain novelties of construction and arrangements of parts, as hereinafter set forth and pointed out in the claims. While the `preferred form is illustrated in the accompanying drawings, yet it is to be understood that minor changes may be made without departing from the scope thereof.

In the accompanying drawings,

Figure l represents a front view of my improved device,

Fig. 2 represents a side elevation of the same, showing the means for holding the device in an upright position.

Fig. 3 represents a front view, with the front plate removed, showing all the parts in their operative position, with the lugs of the front plate in section engaging with the notches of the rear plate.

Fig. 4: represents a front view of the rear plate, showing the bearings and notches for receiving the operative parts, and the front plate.

Fig. 5 represents a sectional side view, taken on lines a-a of Fig. 1.

Fig. 6 represents a sectional end view, taken on lines b-b of Fig. l; and

Fig. 7 represents a fragmentary sectional view taken on lines c--c of Fig. 3, illustrating an integral projection formed on the rear plate, designed to engage with suitable apertures in the apertured dials, to prevent accidental movement thereof.

Similar numerals of reference refer to like parts throughout the specification and drawings.

The improved calendar is preferably made of flexible metal of any kind, such as brass, tin, copper or aluminium, and the parts are of such shape as to' lend themselves readily to manufacture by the use of suitable punches and dies, from ordinary sheet metal.

My improved calendar consists essentially of a frame, in which the working parts are contained, the working parts consisting of two disks or dials, preferably lof the. same diameter, upon one of which are printed the figures l, 2, 3, 4, 5, 6, 7, 8, 9, 0, and on the other are printed the figures 1, 2, 3, 0, and two apertured dials, preferably of different diameters, upon one of which are printed the days of the week, and upon the other are printed the months of the year, and a spring adapted to be engaged by two disks or dials containing the numerals.

In the drawings, the frame in which said working parts are contained, consists of a front and rear plate, designated oy the numerals 1 and 2. The front plate 1 may be made of any suitable material, and with any suitable kind or amount of ornamentation. As shown, it is provided with apertures 3 and 4, designed to expose the number of the day, and an aperture 5, designed to expose the month, said aperture being preferably located below the apertures exposing the number of the day. A. suitable recess or cut-out portion 6, is provided at the top of the front plate l, designed to expose the day.

The front plate l is further provided with a marginal iiange 7, from which project a plurality of integral ears or lugs S, the purpose of which will be hereinafter described. The marginal flange 7 is further provided with cut-away portions 9, at the top and sides, for convenience in manipulating. the

respective dials and apertured dials, which register with said cut-away portions 9, as shown in the drawings.

The rear plate 2 is provided along its marginal edges with a plurality of notches 10, corresponding in number to the ears or lugs 8 on the front plate, designed to receive said ears or lugs 8, which are clenched over on the back of the rear plate 2, to secure the front plate 1 to the rear plate 2. The rear plate 2 is provided with a plurality of apertures 1,1, 11, 11, 12, 12, 13, 13, 13, each aperture surrounded by a circular wall, said circular walls forming integral parts of the rear plate 2, and projecting` inwardly from one side of said plate to a height suilicient to form suitable bearings, upon which the disks or dials and apertured dials are rotatably mounted.

The inner circumferential edge of the apertured dial 14, on which are printed the days of the week, engages with the circular walls of the apertures 11, 11, 11, by means of which the apertured dial 14 is positioned and rotatively mounted upon the rear plate 2. The inner circumferential edge of the apertured dial 15, on which are printed the months of the year, engages with the circular walls of the apertures 13, 13, 13, by means of which the apertured dial 15 is positioned and rotatively mounted upon the rear plate 2.

A fiat spring` 16, the ends of which are provided with notches 17-17, is positioned and secured upon the rear plate by causing the notches in the ends of the spring to engage with the circular walls surrounding the apertures 12, 12. The dials 18, 18, on which are printed the days of the month, are each provided with a suitable aperture designed to receive lthe circular walls surrounding the apertures 12, 12, and upon which said Vdials are rotatively mounted above the ends of the spring 16. The flat spring 16, in close proximity to the notches 17, is provided with projections 19, which are designed to engage with apertures 20 formed in the disks or dials 18, 18, thus preventing the accidental. moving of said disks or dials 18.

A lug 21 integrally formed on the front plate 1, and located centrally on said plate, is adapted to enter an. aperture 22 located centrally in the rear plate 2, which form means for additionally securing said front and rear plates together, and serve as a means for properly spacing the said front and rear plates.

The rear plate 2 may be provided with an angular extension 23, which may be utilized as a support. The rear plate-is further provided with two seats 24, which may be formed on said plate in any desired or convenient manner, the height of which are approximatelyin line with the top of the apertured dial 14, on which are printed the days of the week, and which form convenient supports for the apertured dial 15, on which are printed the months of the year. These supports 24 serve to maintain the apertured dial 15 in a level position, and further prevent said dial from binding when all of the parts are. in their assembled position.

The assembling of my device is very simple and as follows: The apertured dial 14 is secured to the rear plate 2 by causing the inner circumferential edge thereof to engage with the circular walls of the apertures 11, 11, 11. The apertured dial 15 is then placed over the dial 14, with its inner circumferential edge engaging the circular walls of the apertures- 13, 13, 13. The notched ends 17 of the :fiat spring 16, are then caused to engage with the circular walls of the apertures 12, 12, whereby said spring is positioned and secured to the rear plate 2. The dials 18, 18 are then mounted on the circular' walls of the apertures 12, 12 by means of a central aperture in each dial, the projections 19 formed near each Lend of the spring engaging with one of the apertures 20 formed in the disks or dials 18, in which manner the dials18, 18 are secured to the eircular walls and spring, to prevent accidental rotation thereof. It will of course be'understood that a portion of the periphery of each disk or dial is exposed outside of the mar'- ginal edges of the frame. The front plate 1 is then secured to the rear plate 2 by passing the lugs 8 and the lug 21 through the notches 10 and the central aperture 22, and then clenching the same over upon vthe rear of the rear plate 2.

The back pla-te 2 .may be further provided with stuck-up points 25, designed tov engage with suitable apertures 26 formed in the vapertured dials 14 and 15, in order to prevent accidental movement of the same.

The operation of my improved calendar is as follows: The parts heilig in the position shown in Fig. 1 of the drawings, with a portion of the periphery of each disk or dial extending through the cut-away portions 9, the operators inger engages the exposed periphery of the apertured dial 14 and moves it iuitil the desired day is exposed in the recess 6. The operator then, in the same manner, .moves the disks or dials 18, 18 until the desired date is exposed in the apertures 3 and 4. The apertured dial 15 'is then moved untilv the desired month appears in the aperture 5. y

Experience has demonstrated that the organization above described is a highly elli cient one, andwhile the device described is the preferred embodiment of my present invention, I do not care to restrict myself to the exact details of constructions, combination and arrangement herein set forth, it being obvious that minor variations thereof,

not involving the eXercise of invention, may be made by any skilled mechanic, and such departures from what is herein described and claimed, I consider within the sco e and terms of my claims.
